How many times have you joined a game, where the person on point, keeps running ahead?
By doing this, all that they are demonstrating, is their bad leadership qualities. Running ahead, when on point, shows a total lack of consideration for the rest of their battle brothers, who may be engaged in a rear guard action or sealing doors. These rear guard people, then do have to run, in-order to catch-up. However, if a stupid point man keeps running, then they can never catch-up. All it achieves is the team being split up. The only time a person on point should run, is when they don't have the weaponry, or shields, to deal with a turret, and need to seek cover.
Please, people on point, stop running ahead, and give some consideration to your squad members. Also, it looks more cool to walk than to keep running everywhere.
Rest assured, anyone who joins a game that I host, where I'm on point duty, I'll never leave a team mate behind.
